The pitch about the Go Windsurfer is "This simple innovation transforms the idea of adding daggerboard system to a freeride board as it no longer compromises full planing performance; no more draggy, slow, sticky feelings. The GO Windsurfer, with the daggerboard removed, planes and rides just like a board without a daggerboard box."

Why do you claim that "it will limit you to longboard style/rig steering until you get another board"?

My experience is that even boards like the Kona One and the Phantom 320 have no such limitations!
